I've created the database file and made sure it's there.
I even created the user with '-f /etc/sasldb2' just to make sure it took.
No errors there.

These are the permissions for the file.
-rw-rw---- 1 root sasl 12288 Dec 27 19:32 /etc/sasldb2


I created the password hash via

perl -MMIME::Base64 -e ' print encode_base64("username\0username\0password");'

Any suggestions on what to look for
